methylene chloride, glycol ether, or halogenated hydrocarbons. Solvents
used onsite shall have a flash point greater than 60 degrees C. 140 degrees
F.

Leak-tight Wrapping
Two layers of 0.15 mm 6 mil minimum thick polyethylene sheet stock shall be
used for the containment of removed asbestos-containing components or
materials such as reactor vessels, large tanks, boilers, insulated pipe
segments and other materials too large to be placed in disposal bags as
described in DETAIL SHEET 9B. Upon placement of the ACM component or
material, each layer shall be individually leak-tight sealed with duct tape.
1.23.7
Viewing Inspection Window
Where feasible, a minimum of 1 clear, 3 mm 1/8 inch thick, acrylic sheet,
450 by 610 mm 18 by 24 inches, shall be installed as a viewing inspection
window at eye level on a wall in each containment enclosure. The windows
shall be sealed leak-tight with industrial grade duct tape.

Wetting Agents
**************************************************************************
NOTE: Review the abatement methods to be employed
and edit the paragraph accordingly.
**************************************************************************
Amended water shall meet the requirements of ASTM D 1331. Removal
encapsulant (a penetrating encapsulant) shall be provided when conducting
removal abatement activities that require a longer removal time or are
subject to rapid evaporation of amended water. The removal encapsulant
shall be capable of wetting the ACM and retarding fiber release during
disturbance of the ACM greater than or equal to that provided by amended
water. Performance requirements for penetrating encapsulants are specified
in paragraph ENCAPSULANTS.
1.23.9
Strippable Coating
**************************************************************************
NOTE: Review abatement methods to be employed and
delete if not required.
**************************************************************************
Strippable coating in aerosol cans shall be used to adhere to surfaces and
to be removed cleanly by stripping, at the completion of work.

ENCAPSULANTS
**************************************************************************
NOTE: Materials in various forms are used to
chemically or physically entrap asbestos fibers in
various configurations to prevent these fibers from
becoming airborne. There are four types of
encapsulants, as follows, which must comply with
performance requirements as specified herein;
a. Removal encapsulant (can be used as a wetting
agent).
